Gender‐based outcomes of coronary bifurcation stenting: A report from the National Readmission Database

Background There is a paucity of data focusing on women's outcomes after percutaneous coronary interventions (PCI) for coronary bifurcation lesions (CBLs). Methods Patients who received PCI for CBLs in the context of acute coronary syndrome (ACS) during the period of 01 October 2015– 31 December 2017, were identified from the United States National Readmission Database. The primary endpoint of this study was in‐hospital major adverse events (MAEs). The secondary endpoints were in‐hospital mortality, vascular complications, major bleeding, post‐procedural bleeding, need for blood transfusion, severe disability surrogates (non‐home discharge and need for mechanical ventilation), resources utilization surrogates (length of stay and cost of hospitalization), and 30‐day readmission rate. A 1:1 propensity score matching was used to compare the outcomes between women and men. Results A total of 25,050 (women = 7,480; men = 17,570) patients were included in the current analysis. After propensity score matching, women had higher in‐hospital MAEs (7 vs 5.2%, p
